Title: Navigation aid apparatus
IPC: G05D1/02
Filed: 1955-07-15
Abstract: 791,987. Automatic steering control systems. SPERRY RAND CORPORATION. July 15, 1955 [Aug. 2, 1954], No. 20544/55. Class 38 (4). In a system for steering an aircraft towards and along a radio beam, the ratio of the magnitudes of signals representative of heading deviation and displacement from the beam is increased when displacement from the beam is reduced below a predetermined value. As shown, a visualomni-range radio receiver 10 in an aircraft produces a D.C. signal dependent on lateral displacement of the aircraft from a course having a bearing determined by a selector 12 relative to the transmitting station. This signal, which is converted into an A.C. signal in a modulator 16 and amplified at 18, controls a motor 20 which, by virtue of a follow-up potentiometer 26, takes up a position dependent on the displacement from course, so that a corresponding signal derived from a potentiometer 32 driven by the motor is applied through a potential divider 34 and amplifiers 38, 58 to turn the aircraft towards course by operating on the bank channel of an automatic pilot (not shown). The followup system 14 tends to smooth out transient effects and a control term dependent on rate of change of displacement is introduced from a generator 22, driven by motor 20, through a potential divider 40 to amplifier 38. The magnitude of the signal applied to the bank channel of the automatic pilot is limited by a diode arrangement 56. The course of the aircraft is also corrected by applying a signal from a synchro pick-off 46 associated with a gyrocompass 44 through synchros 48 and 50 to amplifier 38 so that any deviation of the aircraft from a heading determined by the setting of synchro 50 results in course correction. When the aircraft is substantially on course so that motor 20 closes contacts 84, 86 and a relay 90 is de-energized in the absence of course correcting signals, a relay 80 changes over from the position shown so that (a) contacts 36 reduce the course displacement signal from potential divider 34, (b) contacts 42 increase the rate signal from potential divider 40, (c) contacts 64 reduce the bias of diode arrangement 56 so that the limiting value of the bank signal is reduced, (d) contacts 68 apply the displacement signal through an amplifier 72 to operate an integrating motor 74 which positions synchro 48 so that the heading signal is modified by persistent lateral displacement from course to counter the effect of cross-winds. During the time that the aircraft is seeking its proper course, before relay 80 operates, contacts 68 connect the output of a potentiometer 66 driven by motor 74 to the input of amplifier 72 so that synchro 48 is maintained in a zero position. During banking, relay 90 also serves to disable a gyro-vertical of the automatic pilot. A relay 96 switches in the control system automatically during the initial approach. Specification 647,469 is referred to.

Title: A device for preventing vehicle wheels from skidding
IPC: B60B39/00
Filed: 1966-05-10
Abstract: 1,121,561. Automatic regulation of braking. GRAUBREMSE G.m.b.H. and TELDIX LUFTFAHRT AUSRUSTUNGS G.m.b.H. May 10, 1966 [May 14, 1965], No.20548/66. Heading F2F. A device for preventing vehicle wheels from skidding comprises a flywheel 19, the rotation of which relatively to a shaft coupled to the vehicle wheel is transformed into axial displacement of an operating member 7 on the axis of the shaft by means of two serially co-operating two-armed levers 6, 18 fulcrumed on pivots and which form a system participating in the rotation of the shaft about its axis. The levers are pivoted about axes normal to each other and mounted in a member 16 just on the shaft. A lug 16a on the member is normally biased against a stop 26 on the flywheel by a spring 27. Above a threshold value of retardation the member moves away from the stop 26, the lever 18 being rotated by the flywheel face 19a to rotate lever 6 about its axis (6a, Fig.l, not shown)and move'the rod 7 axially to close a switch (13, 14) to energize a solenoid, optionally through an amplifier, to control the brakes appropriately. A spring 30 prevents oscillation due to rebound. In a modification the stop 26 is replaced by a  permanent magnet (32, Fig.3, not shown). The push-rod may, alternatively, operate a valve.

Title: Improvements in purification of sugar solutions
IPC: C13B20/12
Filed: 1960-06-13
Abstract: 889,823. Purifying sugar solutions. AMERICAN SUGAR REFINING CO. June 13, 1960 [June 22, 1959], No. 20680/60. Class 127. In a continuous purification process, hot sugar solution of constant viscosity is passed upwardly and uniformly through an elongated vertical column, e.g. 30 to 40 feet high and 12 feet in diameter, in counter-current to a downwardly flowing bed of adsorbent, e.g. bone char or activated carbon. In the arrangement shown diagrammatically, sugar solution, preferably having a pH above 7.0, e.g. between 7.2 and 7.5, is freed from dissolved gases, e.g. air, and introduced via an inlet 2 near the bottom of an insulated and heated column 1, and is distributed by pipes 3 to flow upwardly through the column to a purified solution outlet 4 via an overflow device 5 and trough 6, whilst adsorbent is fed through a series of lines 7 to pass downwardly, through soaking chambers 8 and a body of purified sugar solution, to reach the top level 32 of a bed of adsorbent, which is expanded, e.g. to 5% to 15% of its settled volume, by the upwardly flowing sugar solution. From the conically shaped bottom of the column, a slurry of spent char and sugar solution passes through lines 10 and a line 11 to a series of crossover pipes 12, having control valves and located at different levels, to regulate the slurry overflow, both to a line 13, leading to a de-liquoring device 14, and to a by-pass line 15a. Deliquored spent char and slurry combine in a line 15 for downward descent through a desweetening column 16, in counter-current to an upward flow of water fed in near the foot of the column 16 through an inlet 17 and distribution pipes 70, sweet-water e.g. around 30‹ Brix, leaving the column via a collecting trough and outlet 18. Bone char slurry leaves the column at the bottom via lines 19, 20 and cross-over pipes 21 to enter a de-ashing column 23, constructed similarly to column 16, from which waste water leaves to the sewer through an outlet 25, whilst de-ashed char passes through line 26 and cross-over pipes 27 for filtration and regeneration. More than one column 1 may be used if desired. Lines 9, 83 extend into the columns to enable samples of liquor to be drawn, and 38, 80 represent differential pressure cells to determine and regulate the level 32. The sugar solution to be purified preferably lies between 60‹ and 65‹ Brix, has a temperature of from 160‹ to 180‹ F., a viscosity of from 6.7 to 8.2 c.p.s. and is passed upwardly through the column in amount 3 to 10 times the volume of adsorbent passing down the column; it may be adjusted in pH by adding to it lime or calcium sucrate. Suitable forms of apparatus are described in detail and, in an alternative procedure, the adsorbent fed to the top of the purifying column may be formed into a slurry with purified sugar solution before admission to the column. U.S.A. Specifications 2,352,932 and 2,735,823 are referred to.

Abstract: 782,948. Mechanical presses. SCHLOEMANN AKT.-GES. July 18, 1955 [Aug. 10, 1954], No. 20695/55. Class 87(2). [Also in Group XXII] A control mechanism for a press comprises a control member 15 driven by the moving platen 6 of the press and which, upon reaching one of its two end positions, alternately actuates one of two control elements 18, 19 of a change-over device 15, 20, one of said elements stopping the upward movement and starting the downward movement of the platen, whilst the other acts vice versa, the control elements being collectively adjustable in relation to the control member for varying the vertical position of the stroke. A rack 8 connected to the platen 6 drives a pinion 9 on a shaft 10 which may be connected through a disengageable coupling 11, 14, actuated by a solenoid 12, to a control shaft 13 carrying the control member 15. The latter co-operates with contacts 18, 19, 19a, &c. on an arcuate plate 20 said contacts controlling valves which effect the reversal of the press platen. The shaft 13 is biased by a spring 17 to position the control member 15 into contact with the control element 18 which causes the platen to move downwardly. Upon engagement with the contact 19, the downward movement is stopped and reversal takes place. If a longer stroke is required the control elements 19a or 19b are used instead of the element 19. The arcuate plate 20 may be rotated about the axis of the shaft 13 by a worm 23 and driven by an electric control motor 24 for varying thevertical position of the stroke. A stroke indicator 26, 27 is provided. The control elements 18 and 19 may control the press by hydraulic means instead of electric. The press may be a mechanical or hydraulic press.

Classes 80(2) and 80(4) A safety arrangement on a press for disengaging the machine coupling when an overload occurs is associated with a shearing piece safety device, a shearing pot 30 is arranged between two parts 3, 4<SP>1</SP> of the press connecting rod which is coupled at 11 to the press ram. The part 4<SP>1</SP> of the connecting rod is secured in the sleeve like part 3 by a retaining nut 7 and has 'a screw part 32 for tightening against a shearing ring 31 engaging the pot 30. A plate 40 secured to the sleeve 3 carries a push button switch member 55 operating between contacts 56, 57 and actuated by a rod 54. The rod 54 is adapted to be acted upon by a spring- loaded lever 47 controlled by a two-armed catch lever 42, 43. In normal operation the arm 42 is just engaged by a plate 44 on the part 4' of the connecting rod and the lever 47 is retained by arm 43 to keep contacts 57 closed and an electromagnetically operated coupling engaged. On an overload occurring the shearing pot 30 is first elastically deformed and the part 4<SP>1</SP> of the connecting rod moves relatively to part 3 to operate catch lever 42, 43 to release lever 47. The contacts 57 are opened and contacts 56 closed to open the circuit of the coupling which is thus disengaged. The shearing pot 30 may or may not be completely broken as the catch lever 42, 43 operates immediately on a small relative movement between the parts 3, 4<SP>1</SP> of the connecting rod. The coupling may be hydraulically or pneumatically operated in which case the switch 55-57 will operate on electromagnet to actuate 'a control valve or the lever 47 could be directly connected to a control valve.

Abstract: 595,313. Electric indicating systems. ARNOLD, C. (Standard Oil Development Co.). Oct. 25, 1944, No. 20781. [Class 40 (i)] [Also in Groups XX and XXXVI] In an arrangement for producing a continuous record of small changes in voltage, e.g. due to a pyrometer, light cell or the like, a spark is produced at an instant, during a cycle, dependent on the magnitude of the voltage, the spark passing from a point on a rotating helical conductor to a point on a stationary straight conductor, thereby marking a sensitive paper placed between the conductors at a point dependent on the magnitude of the voltage to be measured. Light reflected from the mirror galvanometer 3 falls on mirror 5 which is rotated in synchronism with helix 11 by motor 15. Light reflected from the mirror 5 passes through slit 6 on to the photo-cell 7 at an instant during the rotation of the mirror 5 dependent on the deflection of the galvanometer mirror 3. The photo-cell output amplified at 8 triggers the gas-valve 10 to produce a pulse amplified at 21 to produce between the helix 11 and the metal plate 13 a spark, which marks the sensitive paper 14 at a point whose lateral position is dependent on the angular position of the helix at that instant, which is in turn dependent on the deflection of the mirror 3. Instead of the rotating mirror 5 and the fixed slit 6, a rotating spiral slit, Fig. 2 (not shown), may be used. Fig. 4 (not shown) indicates how the arrangement may be used to record the absorption spectrum of a sample of material (see Group XX). Reference lines may be produced on the sensitive paper by feeding the grid of valve 10 at appropriate intervals with oscillating current of duration equal to that of one revolution of the helix.
